WebGL2 Nano Currency Proof of Work Generation
See the demo for a working implementation.
WebGL 2 provides bitwise operators unavailable in WebGL 1. These are required for the Blake2B calculation. As of time of writing, WebGL2 is supported in Chrome and Firefox, on desktop and Android. See the WebGL2 compatibility table for more information.
Download the source code from the repository or with NPM.
npm install nano-webgl-pow
window.NanoWebglPow(hashHex, callback, progressCallback, threshold);
Due to using
window.requestAnimationFrame() to prevent blocking the main thread during generation, the browser tab must remain open during generation.
<String>Previous Block Hash as Hex String
<Function>Called when work value found. Arguments:
workwork value as hex string,
nnumber of frames calculated
<Function>Optional. Receives single argument: n, number of frames so far. Return
<String>|<Number>Optional work difficulty as 32bit (default if ommited is
0xFFFFFFF8). Original up to v20 =
0xFFFFFFC0, v21 Send,Change =
0xFFFFFFF8, v21 Receive =
0xFFFFFE00. Max is 64x from original which is
Width, height properties for rendered frames during generation. Larger values will load the graphics card more.
Values must be multiples of 256 but do not need to be the same. (i.e. 512x768 is ok, 510x768 is not)
